Jonathan C Fellers, MD

Psychiatry, Addiction Psychiatry

As an addiction psychiatrist, I work with patients, families, and our health care system to promote high quality evidence-based screening, assessment, and treatment for substance use disorders and co-occurring mental disorders.  Addiction involves both biology and psychology, and I take a particular interest in helping disentangle this complexity. I enjoy spending my time enjoying Maine’s natural beauty, whether it is sailing in Casco Bay, skiing in the Western Mountains, or taking a family walk on the beach.
